Abstract
An assembly for molding and demolding hardened cementitious products comprises a flexible mold and a demolding apparatus. The flexible mold has a top side with separate openings for receiving cementitious material therein for hardening thereof, an opposite closed rear side and a perimeter. The apparatus for demolding the hardened cementitious products from the flexible mold comprises a conveyor, a holding member, a clamp, and a movable member. The conveyor conveys the flexible mold. The clamp grips a portion of the perimeter. The holding member engages the mold. The ovable member moves the clamp and the clamped portion of the mold about the holding member thereby disengaging the flexible mold from the cementitious material.

a conveyor for conveying said flexible mold with said front face down;
a clamp for clamping a portion of said perimeter a holding member for engaging said mold rear side; and a movable member for moving said clamp and said clamped portion of said mold upwardly causing said mold to curve about said holding member thereby disengaging said flexible mold from the cementitious material.
a flexible mold having a top side with separate openings for receiving cementitious material therein for hardening thereof, an opposite closed rear side and a perimeter; and an apparatus for demolding the hardened cementitious products from said flexible mold comprising:
a conveyor for conveying said flexible mold with said front face down;
a clamp for clamping a portion of said perimeter a holding member for engaging said mold rear side; and a movable member for moving said clamp and said clamped portion of said mold upwardly causing said mold to curve about said holding member thereby disengaging said flexible mold from the cementitious material.
2. An assembly according to claim 1, wherein said conveyor provides for conveying said mold in tandem with said movable member moving said clamp and said clamped portion upwardly thereby progressively disengaging said flexible mold from the cementitious material.
3. An assembly according to claim 1, further comprising a pusher for engaging a portion of the cementitious material when disengaged from said mold so as to avoid for the cemetitious material to be raised along with said clamped portion when upwardly moved.
4. An assembly according to claim 3, wherein said pusher comprises a movable bracket movable along the length of said conveyor.
5. An assembly according to claim 4, wherein said movable bracket is connected to a stationary bracket via a movement imparting device for being moved towards and away said stationary bracket.
6. An assembly according to claim 4, wherein said movable bracket is slidable along a guide rail.
7. An assembly according to claim 1, wherein said perimeter of said mold has a flange like configuration.
8. An assembly according to claim 1, wherein said conveyor comprises an upstream surface and a downstream surface, said downstream surface being slightly lower than said upstream surface so as to provide a space between said perimeter of said mold and said downstream surface thereby allowing for said clamp to engage said perimeter.
9. An assembly according to claim 1, wherein said holding member comprises rollers.
10. An apparatus for demolding hardened cementitious products from a flexible mold having a top side with separate openings for receiving cementitious material therein for hardening thereof, an opposite closed rear side and a perimeter, said apparatus comprising:

11. An apparatus according to claim 10, wherein said conveyor provides for conveying the mold in tandem with said movable member moving said clamp and the clamped portion of the mold upwardly thereby progressively disengaging the flexible mold from the cementitious material.
12. An apparatus according to claim 10, further comprising a pusher for engaging a portion of the cementitious material when disengaged from said mold so as to avoid for the cemetitious material to be raised along with said clamped portion when upwardly moved.
13. An apparatus according to claim 12, wherein said pusher comprises a movable bracket movable along the length of said conveyor.
14. An apparatus according to claim 13, wherein said movable bracket is connected to a stationary bracket via a movement imparting device for being moved towards and away said stationary bracket.
15. An apparatus according to claim 13, wherein said movable bracket is slidable along a guide rail.
16. An apparatus according to claim 10, wherein said conveyor comprises an upstream surface and a downstream surface, said downstream surface being slightly lower than said upstream surface so as to provide a space between the perimeter of the mold and said downstream surface thereby allowing for said clamp to engage the perimeter.
17. An apparatus according to claim 10, wherein said holding member comprises rollers.
